Astrobotic gained at least one fan, and I am sure many others by being open and communicative when things went sideways.
It really was amazing to see such transparency. I can hope other companies follow suit but we at least know that one company is that transparent.
Trailblazing transparency. What a great term. Astrobotic, don’t get discouraged and thank you for setting the communication bar so high for us aerospace nerds.
Thank you Astrobotic for being transparent and providing timely updates. Thanks Adrian, Ryan C., and Kevin for this summary.
Thanks to Astrobotic for all the updates and keeping us space enthusiasts in the loop…more space knowledge more better.Hope they can continue and reach the moon in the near future. Moon! Moon! Moon!
Peregrine Was A Test And That Means That We Will Learn From This.We Will Also Learn From Any Mission.
I wish Astrobotic all the best with their Griffin space probe
Thanks for the transparency. Space
Is hard!
I felt like I was part of that mission sitting in my lounge in Aus. So cool even though the primary objective was not met.
January was a bad month for lunar landers as it turns out. Peregrine fails, spectacularly. Then, JAXA's lander (SLIM - Smart Lunar Investigating Moon) landed, and apparently wound up upside down, or backwards, with its solar panels facing away from sun. Space is hard. Landing on extraterrestrial bodies is REAL hard!
I’m really grateful to have had the chance to send a payload aboard Peregrine. Although the mission didn’t end the way we expected it was the journey of a lifetime and it was amazing getting to know the Astrobotic team. I will definitely continue my mission of landing on the moon with them on a future mission.
Excellent report on this mission! And I seriously mean excellent! So much info. Absolutely no fluff. This is better than anything I’ve seen on the news in years. Bravo NSF!
NSF and Astrobotic, y'all rock! Peace
I don't know how long they worked on the craft and its instruments, but it had to have been very painful to lose it after all they went through and a remarkably successful launch. I suspect they will regroup and come back stronger -- here's hoping!
Thank you. Excellent work.
Good round up. Thank you.
It was Apollo 13 minus the astronauts! Smilar problem and similar result. I wonder how much Apollo lore was influencing their actions and decisions. Great job!
That was a very cogent explanation of Astrobotic's mission. It's a shame it was able to complete its primary goal of landing on the moon. However, under the circumstances, Peregrine was able to perform a number of experiments and therefore wasn't a complete loss. Thank you, Adrian, Ryan and Keven.
Thanks for the updates
Three words: Space is hard
Thank you
Great video
I am now hoping for a quantitative comparison of all the various moon landing attempt of the past decade. I know there is more to come as well.
It would be interesting to compare which system failed and what mitigations were put in place for each
I know this would have added to the complexity, but putting the solar panels on 4 "petals" that are hinged on the edges of the spacecraft would have been better. Opening the solar petals would face them backwards, which is where the Sun is going to be (roughly) if you want to land and be on the Moon for days while in daylight.
The Pocari Sweat can (seen in the last shot) was a time capsule that would be dropped on the surface on the moon, it was originally planned for 2015.
13:11 Hehe: "Perigene" which I think is a blending of "Perigee" and "Peregrine" 🤣
Why do they not make at least two? First one fails the second is ready to go! I learnt this from the Film Contact Lol
lol suboptimal. Awesome.
12:23 What a saga. But what I want to know is, why is there a can of "Pocari Sweat" (a popular Japanese drink) showing in that 2nd lander image?
You can notice the bent strut in the picture. how did that happen.
As a retired mechanical engineer, I admit I don't know much about spacecraft design, and I certainly don't have a copy of Astrobotic's Peregrine drawings. That said, for terrestrial engineering, designing a system with such an obvious single point failure seems a bit unusual. To me a second in-line backup valve and a pressure relief system would at a minimum been installed. Clearly weight limitations need to be considered. However, valves fail to seat at a high frequency, especially, it seems, spacecraft valves. Critical functions ought to have critical point redundancy.
By the way, I'd be curious to know what you think about what The Angry Astronaut reported that NASA ordered Astrobotic to crash Peregrine into the Earth's atmosphere.
Peregrin in no way “completed its job.”
Weren't there ashes on board, of famous people?? Where are they now??
respect from china
What happened to the dna (or ashes?) of the people that were supposed to end up on the moon?
Bent Strut?
And it was so easy to go to the moon 50 years ago 😂
Is there a known surface gravity measurement where the Chinese have landed on the far side of the moon? And what about the near side where the Japanese just ‘landed’? Anyone!
No reaction wheels on the lander?
so peregrine failed so who will succeed intuitive machines nova c or astrobtics next griffin lander time will tell. im hedging my bets on astrobotics griffin lander i dont think intuitive machines will be able to be succesful on first attempt with nova c but hoping they prove me wrong
RIP Peregrine, you tried to make it to the moon, but failed, if you launch another one hopefully you get there next time.
😢
Bad disconnect damaged the payload.
A fuel leak destroys all hope of success.
First
What is your opinion on the story that there is more going on behind the scenes, and less transparency than we originally thought?
i guess china is better at landing things on the moon now too... falling behind
first
Definitely that crypto payload data corrupted the lander hardware 😏
Second stage noise cone was to long. put to much sress at connection point. line to tank was cracked open venting tank the tank was crushed as well may have damage one of the bolts on the connection flange. the picture was facing the wrong direction as well.
why are my comments not be sent.
Stupid solar panel design... They should be on struts that orient the panels & not need propulsion to keep sun directed...
2024 already sucks
The original flight plan was wrong, they should of gone straight to the moon.
Pin this
PereGRIN. Not PereGREEN.
So the United States STILL hasn't gotten a lander to leave orbit. Artemis I did indeed leave orbit, but it wasn't equipped with a lander. Its mission was just to circle the moon and come back. Even that was only done after years of delays. Artemis II is expected to be done in late 2025 which which is even more delays.
Meanwhile, Japan, India, China, and Russia have all gotten landers to the moon and some have had successful landings. America, having been the ONLY country to put men on the moon, not once, but several times, is now embarrassing itself! Shouldn't we know how to do this? Aren't we the experts here? Hell, even Mexico is planning a launch in one month that will land robots on the lunar surface! Mexico!
NASA is a joke.
Everyone is handing out participation trophies. Knowing the moon was not there to catapult the Peregrine around and back to earth in combination with the picture of the earth in the distance, we can safely say the vehicle is headed out of the solar system or never really left earth’s orbit. This complete lack of transparency, one picture of the damaged vehicle and one picture of the earth, with a quick explanation of the lighting, leaves one to believe the truth may never be told.
Peregrine was put into a trans-lunar injection (TLI) orbit by Vulcan. This is a highly elliptical orbit around the Earth (with the Earth at one of the foci of the ellipse), that intersects the Moon's orbit at or near its apogee (the farthest point from the Earth in Peregrine's orbit). This is a very typical scheme for satellites or landers aimed at the Moon.
An additional burn, by Peregrine itself, would be necessary to then shift from TLI at apogee to an orbit around the Moon. That burn never occurred, due to Peregrine's propulsion failure. Which is why Peregrine remained in its TLI orbit around the Earth, and why it thus swung back and returned to Earth's vicinity. Astrobotic then used Peregrine's remaining propellant to alter the perigee (closest approach) point of its orbit, to be inside Earth's atmosphere - causing Peregrine to reenter and burn up in a controlled manner.
